These tires compete with any other off road tire I have ever used. They are on my 2006 ram 3500 SRW 4x4 with a 6 inch lift. They are great in deep snow (Elk Season). Work great on dry loose ground (Deer Season). And they work awesome in shallow or deep mud water crossings etc. (Goose, Duck, Pheasant season) And I have 34000 miles on them as we speak. Will buy another set!

These tires just won't wear out. I've had them for almost 3 years and they still have at least 3/4ths of the tread left. As a mud tire they suck, the hard rubber slips and slides on rocks. The tread looks as if it will work good but compared to my old BFG mud tires they just don't work as well. They are like a more aggressive all terrain tire when it comes to off road and don't even come close to a super swamper.
For people that want the mud tire look without the horrible tread wear this is the perfect tire but if you're getting this to drive out on wet grass or try to go through a huge mud hole you're in for a surprise and a bad time.
In the snow they actually work pretty well.
They are quiet for a mud tire.

Bought a set of 33 12.5 R17 for my 4 X 4 Suburban, got 90K plus miles out of them driving a lot of freeway miles to the surf, snow, Sierra's for backpacking. Bought another set, almost 80K rotating like crazy. These developed cupping pretty bad. Bought another set and started cupping really bad right from the git go. At 45K they said they didn't have enough weight in the shop to balance them. The tread's almost gone anyway. One shredded itself. Drove about 120 miles to a concert round trip, woke up in the morning and the side walls were shredded and the rim was sitting on the ground. I've got a 60 gallon compressor sitting right were I park this and my work truck just so I can check tire inflation and use air tools to rotate tires easily. It's not like I was driving around on a flat tire. I don't drink or take drugs either. I should probably find a tire that is not so squirrelly in the snow anyway. The great tire was made pre-recession, since then it's been junk as far as I'm concerned. Which really bothers me because I'd like to see Cooper succeed.
